Matt said: "I guess it is the "doc:element/doc:element/doc:field" thing that is mostly what it throwing me." More DSpacey people than I can probably comment more knowledgeably on this, but this seems like less of an OAI-PMH thing than a DSpace thing. It looks like maybe DSpace stores metadata internally in a generic metadata/element/field structure like Bridger showed (with doc namespace): <doc:metadata> <doc:element name="example"> <!-- ignored! --> <doc:element name="dc"> <doc:element name="blahBlahBlah"> <!-- ignored! --> <doc:element name="type"> <doc:element> <doc:element> <doc:field name="value"> <!-- get the value of this element --> ...and the select is pulling the information it needs for the <dc:type /> element in the OAI-PMH output out of the internal DSpace structure.
